I am getting 550 KB/s when using a wired computer through the WRT54GL. Wireless notebook downloading the same 10 MB file, I am only getting 180 KB/s. What is wrong and how can I fix this? My internet connection is a 10 mbit line and notebook is getting excellent signal strength to router. Currently, only running default linksys router. Is ti time to try a 3rd party firmware? Any tips would be great.
